Be it lznown that l, ltliornxni. ll. BIRMING- HAM. a cit zen of the United States, and a resident o Yonkers. Vi estchester County, and State of New York, have invented certain new and. useful Improvements in Attachments for Pile-Fabric Looms, of which the following is a specification.

This invention relates to an attachment for ile fabric looms.

In the manufacture of one type of pile fabric the pile is out by knives or cutting edges of pile wires.

This invention has for its object to provide simple. inexpensive. and effective device which may be easily applied or at taohed to looms of the type defined and which will.- render the operation of the. loom more certain and eflicient.

Another object of the invention is to provide a. loom attachment that will positively and effectively position the pile wires and retain them in the proper spaced relation until they are seized and held by a weave of the fabric.

Another object of the invention is to provide an attachment of the character described that will be quick and snappy in its action.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application and in which- Fig. 1 is a top plan view ofa portion of a pile fabric loom having my attachment mounted thereon.

Fig. 2 is an elevation, partly in section, of the pile wire positioning attachment.

Fig. 3 is an end elevation of the construction shown in Fig. 2.

4 is a plan view of the attachment shown in Fig. 2.

5 is an elevation, partly in section, of one end of the attachment shown in Fig. 2 the parts being shown in Fig. 5 at another stage in the cycle of operation of the device.

Fig. 6 is an elevation showing another form of pile wire retaining member.

7 is an elevation showing another modification of a pile wire retaining mem her and Fig. 8 is top plan view showing the attachment swung to inoperative position.

Referring to the drawings, 1 have shown in Fig. 1 somewhat diagrammatically a portion of the loom, the frame being shown at.

detail in Figs. 28 inclusive.

Serial no. 536,662.

10. woven fabric at 11, and take up roll at 12. I have also shown longitudinal fibers or warp threads 13, lay 14, a reed frame 15 mounted on the lay and having posts 16 adapted to engage the pile wires in aman ner hereinafter described.

The filling or transverse fiber is supplied by the shuttle 17 which is reciprocated across the frame in the usual manner.

The parts of the loom above described operate in the usual manner and the lay moves back and forth lengthwise of the fabric to beat up the fabric.

In this type of loom a plurality of pile wires 18 is used, these wires being inserted across the weave as shown in Fig. 1. Each wire has formed thereon adjacent one end a. cutting edge which cuts the pile as the wire is withdrawn from the fabric. In order to assist the reed frame to position the pile wires and to insure their proper alinement of the pile wires an additional upright bracket 20 is mounted on the lay in a posi tion to engage the free ends of the pile wires on the forward oscillation or movement of the lay and reed frame.

It is essential that the pile wires and knives carried thereby be held in correct position with reference to each other and to the fabric so that when these wires are withdrawn the fibers will be properly severed to give the pile effect to the fabric.

To att in this end I provide a device for receiving, positioning and holding the free ends of the wires. This device is shown in The device has been shown as an attachment which con sists of a bracket having a plate 21 adjustably secured as shown at 22 to the loom frame and arm 23 having one end slotted as shown at 24: and retained on the plate 21 by a bolt 25 having a head 26 at one end and having its opposite end threaded to re ceive nuts 27 As clearly illustrated in the drawings, the arm 23 is adapted to slide longitudinally by reason of the pin and slot connection and in its operative position as shown in Fig. 4, the free end of the arm is positioned under an overhanging lug 28 formed on the plate 21. An upstanding lug 29 formed on the opposite side of the plate engages the other edge of the arm 23. In order to prevent endwise movement of the arm 23 in a. direction to the right (see Fig. 4) I have provided a latch comprising a resilient or spring strip 30 secured to the 7 member 42.

bottom of the plate 21 and having a lug 31 formed on or secured to its free end. This lug is so positioned as to engage an edge 32 of a' laterally ex ending portion 33 of the arm when the arm is in the position shown in Fig. e A tab 34L is also formed on or secured to the lug 31 to ilacintate the releasing of the latch when the arm is to be swung to inoperative position. In order to provide for the swinging oi the arm the end thereof is rounded as shown at 35.

At its free end or the end remote from the portion just described the device has secured thereto means for receiring positioning and retaining the pile wires in their proper spaced relation. The arm 2-3 has a portion 36 which terms a track upon which the ends of the pile wires rest and are moved during the operation of the loom and the forward movement of the fabric. A projection 70 from one side of the track 36 ailords a ready grip for swinging the arm aside and I a pro ection. 71 from the opposite side forms a support under the selvage for the pile wires, to hold the wires when they are lirst inserted. The positioning means is disposei'l above the track and is mounted on the free end of the arm l0 which is secured as shown at 4:1 to the arm 23 and is preferably formed of resilient material or of material having some elasticity. @n the free end oi? this arm is secured a cylindrical or tubular member 42 in which is reciprocably mounted a rod having an enlarged end let adapted to engage and be guided by the cylindrical A spring 45 engages the end 44 and exerts a downward pressure thereon. The downward movement is limited by means of washerslti and nut 47 carried by the free end of the rod .43.

On the lower end of the member ell; is mounted a foot or shoe 48 having a cam surface on its wire receiving edge whereby the pile wire will raise the shoe during its forward movement with the fabric on the loom. its rear edge, as shown particularly in Fig. 5, the shoe 48 has formed there in a recess 50 adapted to receive one end of .a pile wire receiving and positioning member 51.

The member 51 is reciprocably mounted on the shoe 4S and has a portion 52 disposed in a slot 53 in the shoe and an oppositely extending shank 54 which extends through an opening in a laterally extending lug or flange 55 formed on or secured to the shoe. The portion 52 and the slot 53 may be dovetailed if desired. A spring 56 is positioned on the shank 54 between the lug 55- andv the member 51 and this spring exerts a iorce in a direction to move the member 51 into engagement with the shoe 4L8.

The pile wire positioning member 51 has formed therein a notch 5? adapted to re celve a pile Wire and from the showing in Figs. 2 and 5 it will be noted that by reason of the fact that a portion of the member 51 seats in the'recess' 50 in the shoe and also by reason of the contour oi? the shoe a pile wire in passing beneath the shoe will be guided intoand seat in the notch 57. The member 51 has also formed thereon beyond the notch a downwardly extending portion or finger 58 which is so formed as shown in Fig. 5 as to properly space the pile wires a nut.

In order to retain the pile wires in engagement with the track 36 a retaining member 59 is secured to the free end of the arm ll.) and extendsabove the track and substantially in parallel relation thereto for a sutlicient distance to properly retain the pile wires until they are held by the weai'e of the fabric.

in order to retain the pile wires in position after they have passed under the shoe and have been placed in proper position by the member l have provided a resilient latch (50 adjlistably secureil as shown at 61 to the upper surface of the shoe As the wire is moved forward in the member 51 the latch will be raised up and after the wire has passed beyond the end of the latch the latch will spring down to a position shown in 2.

Another form of la ch for attaining this same end is shown in F 6 and in this figure is shown a member 62 which is secured to the free end of the arm l0 in the place oi? the member 5%. The latch has a notch :l'ornied adjacent its free end and this U6) notch is adapted to hold and retain the wires in the same manner as the end of the latch 60. It Wlll'bG understood that the latch 625 wil not move up and down with the foot but will have a certain spring; action due to the resiliency of the arm 4:0.

in Fig. 7 still another :lform of latch is shown and in this form a resilient member i0 is adjustably mounted as shown at 71 on an extension '72 ot' the shoe 4-8. it its free end of the latch 72 has formed thereon a hook Tet having a curved cam edge '75 adapted to be engaged by a pile wire to raise the hook.

It will be noted that the latches and are adiustably mounted so that these latches may be properly positioned with respect to the b at up or extreme forward movement of the lay. The adjustment of the latch will depend on the adjustment of the bracket or attachment on the loom since, of course, the movement oi": the play does not vary.

As shown in Fig. 2 the free end of the track 36 is formed therein a recess or opening 76 to receive the lower portion of the foot 48. A finger grip or handle 77 is mounted on the foot to facilitate the manual lifting of the shoe when desired.

The operation of the device may be briefly iaaaeee described as follows. As will be apparent to those skilled in the art the pile wires are fed into the device or attachment by the action of the loom parts including the reed frame, reed posts, bracket 20, etc. As a wire moves along the track 36 it will engage the edge :9 of the foot 48 and will raise the foot and ride into the notch 57 formed in the positioning member 51. As the wire continues its forward movement with the fabric the member 51 will be movedv to the left (see Figs. 2 and 5) against the tension of the spring 56 as shown in Fig. 5 and the positioning member 58 will properly space the wire from the wire in advance thereof. lihen the wire has been so properly spaced the latch 60 or one of the modified forms of the latch will spring down into the position shown in Fig. 2 and will retain the wire in place. is the next succeeding wire moves along the track and raises the foot 48 the member will also be raised until. the finger 58 is free from the wire last positioned thereby whereupon the spring 56 by a quick positive action will return the member 51 to the position shown in Fig. 2 in which position it will receive the wire passing under the foot. During this movement of the wires along the track the retaining member 59 will hold the wires in engagement with the track. In view of the detailed description of the modifications shown in Figs. 6 and 7 a further statement of the operation outlining the functions of these parts is not deemed necessary.

From the above description it will be seen that a simple, practical and effective device has been provided and that the device will effectively performthe objects of the invention. Furthermore it will be evident that the action of the device will be positive and p y Although certain specific embodiments of the invention have been particularly shown and described it will be understood that the invention is capable of further modification and that further changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claims.
